Be it known that-I, LiioF. ADT, bany, in; the county of Albany and State of `New York, have invented certain new 'and 5 usefulllmprovements in Eyeglasses; and I do hereby declare the following to be -a full, clear, and exact description of the same, reference, vbeing had to the accompanying drawings, forming a part of this specification,andgto the reference-numerals marked thereon. Myv present invention rela-tes to .improvements in eyeglasses, and has for its object -to provide certain improvements' that will enable the use of a 4relatively rigid-bridge for maintaining the proper optical relation between the lenses, and embodying novel -devices that are controlled by the movement of the lenses for producing the requisite :movement of the nose-guardsfor litting and removing the eyeglasses. Y

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter Imore fully explained,'tlie novel features being pointed Aoutiii t-he claims at the end 'of the specification.

My present invention provides an improved lforni of eyecglasses, wherein a comparatively rigid bri ge may be employed to insure Amaintenance of the proper optical relation between the lenses, and wherein provision is made forarelative turning or,

in Figs. 1.t0.5 .comprises generally, a bridge' having preferably the Substantially rigid central porti'on 1, usually bowedforwardly.

to span-the -Wearers nose, and having its arms extending rearwardly; thence turning /vertically and doubling forwardly'to form a pair of resilient lo0psj2 and Sarrangcdpreferably in rear of the planeI of the lenses, the forwardly-extending or free arms of these loops beine rigidly attached to suitable lens-attaching tevices 4 and 5 respectively, `the latter being attached to the lenses, and movahletherewith, as the lenses are tilted or turned. The-nose guards and 7, which may be of any preferred form, have pivotal 'connection at 8 and 9 .to their respective lens-attaching 'deviees, while theV bridge is provided at points intermediate of its central portion and the loops 2 and 3 with screws or projections l() and 11, extending upwardly through longitudinal slots in the lattaching devices, and serving as pivots for their respective nose guards at points preferably in rear of thepins' 8 and 9 respectively, screws being preferably. employed as the guards may be removed by removal of these screws. A mounting of the kind described is fitted to the nose 'hy relatively tilting or turning the lenses in the manner shown in Fig. 2,'tlie relative movement otv thel lenses iii a horizontal plane pern'iitted by .the yielding of the resilient loops 2 and 3 of the bridge, causing relatively inward movement of the. operating pins 8 and 9 relatively 'Spedieation of Letters Patent. l Patented J 5, 1910. l

to the'pivotal centers 10 and 11 on-the intermediate portionsotihe hridge,and this `relative*i'oiiinnent -of the :pins 8 9 and 1.0-11 respectively, will cause aseparating 105 movement ofthe guards about thev pivits 10 and l1 centers, and when the pressure is removed from the lenses, the-.action of the loops 2 land 3 will operate to proximate the nose guards and return the lenses .to normal position.

In' Figsf to 8 inclusive, the end of the bridge is formed .somewhat difllerently from that employedin the form just described, in that the intermediate portions of the bridge are each pivotally attached to the rearward extension 12 of the respective attaching-.device by the pivot pin or screw 13, a yielding or resilient extension 14 of Athebridge extending beyond the pivot thereof and A doubled forwardly -so as to engage a suitable portion ofthe mounting that is movable with vthe lens'such as a part of the lensattaching device. `The nose guard, in tlie l present instance, is mounted substantially the samev as in the form first described, the .pivot pin'o'r screw 15 passing through tlie guardfrom the under side and extending through-a. slot in the lens-attaching device toconnect with the bridge, ata point inter-fr mediate between its central portion and` its vso ` movement .of 3 5 pivot screw 13, the operating pin 16 movable with Vthe lens servingto operate the uard about its-pivot. Y In operating-eyeg asses -embodying Athis form of the invention thev forward movement of the outer ends of the lenses will cause the latter to turn about the screws z 13 as centers, movin the operating in 16- for the ard inward y past the pivtal center 15 115 the guard, and thus producing a relatively separating oropening the 'nose-engaging portion of the guard.

In Figs. 9 and 10 the resilient ends of the spring are formed somewhat differently from those used in the previously described forms, in `that each is provided with one or more convolutions toy form preferably, a

helical loop or coil 17, the increased length of the material affording increased action for the bridgewhen thea-lenses are operated, the operative connection between the guard and the spring and lens-attaching device being, if so desired, substantially the same as that employedin Figs. 6 to 8.

Figs. l1 and 12 show another form of the invention, 'whereinthe ends. of the bridge are extendedin a direction downwardly and rearwardly to a point in rear of the lenses, thence doubled outwardly and forwardly to form substantially horizontal loops or'bends 18, the free ends of theseloops being each rigidly 'connected to its corresponding lensattaching device. 'The latter is` provided vwith an inwardly extending lug 19 having. a pivot 20 foi-the nose guard 21,'an'd thei 'bridge is provided preferably at a point nient is Vimparted to the lenses, the

intermediate its central portion and the loop,

with a lug22 having a pin or projection 23 arrangedlto coperate with the nose guard to turn it whenever relative turning movevistance between the points where the connected to Vthe relatively movable parts o'f-the mounting being adjusted so that the 'requisite movement of the guards may be ob- This form of the invention permits the usev of a long and well shaped bridge, which, if

desired may extend along or t the sides of the wearer s nose, after the manner offthe so called saddle bridge, and this -formtoftained with a given movementof the lenses.

optical -relations is insured, and the necesfl say movement of the nose guards in fitting an removing the eyeglasses, is produced by a comparatively slight turning movement of the lenses, as the arrangement of tlie pivotal centers` of the guards and their op-4 erating pro'ections is such that an amplified or increase movement is given to the guards when the lenses are turned through a givenl angle. Eyeglasses of -this form may beused' to advantage in place of the ordinary spring bridge construction, in that whilethey aioid the requisite movement of the guards', this movement is obtained by a comparatively slight movement of thelenses, 'and liability of breakage of the parts is minimized, and as the resilient portions of the brid e are arranged in rear of the plane of the enses,

the mounting does not a pear conspicuous when viewed from the ront, and thisy is particularly so when the resilient loops are extended rearwardly in a substantiall horizontal plane, as is generally pre ei'able while'by forming these loops as portions of the bridge, ample strength and action is obtained without requiring the use of separate springs and parts liable to loosening or breakage. It is also generally preferable to employ Aa. bridge embodying a relativel rigid central portion, and resilient or yiel ing ortioiis beyond, as the rigid portion of the .grid e not only insuresmaintenance of the Apupi ary distance and other important y optical relations of the lenses as is obtained withspectacles, but when the ends of this rigid portion are arranged to operate above or otherwise closefproiimity tothe flat', surfaces of the attach ng devices, they pro vide rigid guides for insuring therelative turningmovement of the lenses in a given plane. -While it is generally preferable to arrange the nose guards for1 an increased angle of movement when the lenses are the requisite movement of the nose guards.

It will, of course, beund'erstood that those claims, in which the lens attaching. devices are described as being-.mounted to turn or swing on the bridge, are intended to cover .constructions in which the connections 4between the lens attachingdevices and the bridge are in tlieorm o? pivots, instead of resilient loops as herein shown.
